2.10 Connection of fire alarm systems (terminals 45-46)
The effeff emergency exit control unit 720-30 / 32 features an evaluating unit for the direct connection of fire
alarm systems. If fire detectors are connected, when a detector in the line is triggered the door is immediately
released and an alarm triggered.
Usable fire alarm systems
Up to 5 effeff fire alarm systems of series 60 030
(optical smoke detectors) can be connected. The
optical smoke detector 60030 detects smoke
according to the scatter light principle. It is used in
preference wherever smouldering fire may be
expected in the initial phases.
Arrangement of the fire detectors
When arranging the fire detectors, the assumption
is made that a single detector is able to monitor an
area with a horizontal distance of around 2 metres
around the position of the detector.
Connection of the fire detectors
All the detectors planned to make up an alarm
system are connected in a loop, terminating with a

last detector.
Operation without fire alarm system
If the emergency exit control unit is operated
without a directly connected fire alarm system, the
WHUPLQDWLQJ UHVLVWDQFH RI N FDQ EH ZLUHG
directly via terminals 45-46 (=as-delivered status).
